Hai vật m1 và m2 có thể trượt trên mặt bàn
nằm ngang và được nối với nhau bằng dây không
dẫn, khối lượng không đáng kể. Khối lượng 2 vật
là m1
= 2kg, m2
= 1kg, ta tác dụng vào vật m1 một
lực F = 9N theo phương song song với mặt bàn.
Hệ số ma sát giữa hai vật với mặt bàn là 0,2. Lấy
g = 10m/s2
. Hãy tính gia tốc chuyển động.
